Introducing the NEW Cellpro Dual PowerLab 8x2 from Revolectrix

The next step in the PowerLab progression! Built on a proven field tested platform.

INTRODUCTION:

Welcome to the new thread dedicated entirely to an open discussion about the new FMA/REVOLECTRIX Cellpro Dual PowerLab 8x2 Battery Workstation (DPL). The DPL is a dual independent channel work station. You are invited to ask technical questions or inquire about available features to your heart’s content. Answers will be supplied by FMA staff members who performed in-house alpha testing or beta test team members who have logged hours with prototypes of the DPL. Before you start asking questions, take a quick look at the specifications and the feature set of the DPL:

Input voltage: 10-48VDC, reverse polarity protected. Each channel may be operated on separate power supplies using 110V/15A isolated circuits for best results. Additionally both channels may be operated on one power supply provided packs on each channel are isolated.

Major Features:
• Selectable charge rates range 10mA to 40A per channel
• Continuous maximum output power rating, 1344W @ +39.53VDC input voltage, 408W @ +12VDC input voltage
• Using +40VDC to +48VDC input, 1344W output will deliver full current rating (40A) over the full range of output voltage up to 33.6V
• Smart power management allows customer to select between programmable input power sources. Using the Charge Control Software (CCS), choose from several templates to get you in the ballpark, then fine tune the settings. Available settings include power supply input current limit, input low voltage limit, regenerative discharge rate and voltage limit. Dual PowerLab stores 1 set-up for Power Supply per channel and 1 set-up for Battery per channel and asks for verification one time on start-up
• Dual PowerLab does not support charging through node wires only
• Initiate charge, discharge, monitor, and multiple cycles at the DPL or via remote control from the CCS. Graph all major operations when using CCS
• Open Architecture presets allow for customization of any User Preset including show/hide presets on unit, preset name editing, up to 100 parameters control how presets are displayed and charging/discharge/cycling parameter associated with particular batteries and/or charging strategies. Unit includes 25 user preset banks pre-loaded for most major battery type/chemistries, plus 50 library presets
• 0.1mohm voltage resolution allows accurate four point internal resistance measurement of each cell
• Environmentally friendly, regenerative discharge capability of up to 1344W. Unlike traditional methods of discharge, which deplete the output battery’s energy in the form of heat across a transistor, regenerative discharge takes most of that energy and puts it back into the input battery. In other words, when you discharge your LiPo for storage, you will be re-charging your Lead Acid input battery. The total amount of power that you can achieve is limited only by the amount of current that your input battery can accept, or 1344W, whichever is lower
• DPL is also equipped with a traditional, 95W internal discharge capability which is non-regenerative
• Over-sized internal heat sink
• Twin (per channel) 12AWG silicon input power cables with EC5 connectors
• Sendust core toroid capable of 40A continuous input current requirement for maximum output specifications

Other Features:
• Supports Cellpro (FMA) and JST-XH wiring modes
• Adapters available for all popular R/C battery brands
• 2 line, 16 character backlit LCD per channel
• Available opto-isolated PC interface and free Charge Control Software (CCS)
• Intuitive 4 button user interface per channel
• Sleek and attractive high-impact ABS enclosure for maximum airflow efficiency
• Sturdy Aluminum top panel with reliable, recessed tactile buttons
• Quick “preset over-ride access” to common charging parameters like setting charge and discharge current and operational modes of charge/discharge/monitor/cycle(s)
• Additional advanced options menu for adjusting in-depth charging parameters and global options at the unit
• GUI PC software (CCS) allows access to 25 User Presets and 50 Library Presets per channel stored in the unit or available in unlimited number on the P.C. When using both channels, launch two independent instances of the CCS
• Free and reliable firmware updates for the life of the product using the CCS. Firmware updates accomplished on each channel independently
• Automatic Low voltage restore for recovering damaged or over-discharged packs
• Programmable options allow speaker ON/OFF or volume, LCD contrast, customized welcome screen, and much more
• Cold weather mode reduces end-charge voltage; parameters adjustable by customer including ON/OFF, end-charge voltage offset reduction, and temperature
• Expansion Channel mode whereby one DPL primary (master channel 1) can control the expansion channel 2, send over preset information, control all aspects of charging and balancing. This feature is perfect for charging multiple packs of same chemistry and capacity using multiple devices such as split packs connected in series during operation all at unbelievable rates
• Auto charge mode available utilizing advanced fuel gauging technology
• Customizable fuel table lookup values based on presets. Fuel tables can be created using a Fuel Table Wizard in the CCS and applied to individual battery brands by presets for improved accuracy
• Industry’s first Safe Parallel adapters available to maximize available power potential. P.C. software supports up to 9 packs in parallel per channel depending on adapters used. The DPL supports parallel, charge, discharge, cycle, or monitor on each channel. Adapters are peripheral products, available separately, or included as a part of DPL combos

Please note: all specifications and features listed above subject to change prior to delivery.

Retail price for the basic unit currently $369.95 on the REVO USA webstore:

You are good to go with 4 x 12.2 = 48.8 volts. We will update the maximum input voltage after we complete further testing.

It will be good to know what the actual absolute maximum allowable input voltage will be.

Many 48v supplies/inverters etc which are commonly available are designed for battery charging systems. These generally output around 54v or so for float charging etc. So when used as a stand alone supply [ie not for charging batteries] their output is around 53 to 54v rather than 48V DC.

It would be very handy if we can use these types of supplies to power the Dual PL8.

I charge a lot of 6s packs currently with my PL8 with a 24.4 volt power supply. Never had a hiccup with this setup.

Not all 6s charge scenarios are going to be affected. For example if your loaded supply voltage is on the lower side and you don't discharge your packs to 80%, the DC-DC convert may stay in boost mode the entire time. Loaded supply voltage must be viewed in the CCS graph in the supply section, not on the console. Also if you are not looking at the graphs, or current display and not charging from a generator that uses ECO mode, you may miss it.

If you want to send me one of your charge graphs I can tell you more about your specific scenario. PM me for my email address.

Does it have two microcontrollers (one for each side) or is there one microcontroller shared between both charge components?

Two FUIM interfaces, two sets controls, two displays, not internally connected. They can be operated as two separate chargers, or as a single unit with the expansion mode by connecting two FUIM data ports together and enabling expansion mode.
